CARLOS E. CARRIER, OF BERNALILLO, TERRITORY OF NEW MEXICO.

WIRE-BAND STRETCHER AND CUTTER.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed. February 8, 1909. Serial No. 476,681.

To all whom it may concern:

Be it known that I, GARLos E. CARRIER, citizen of the United States, residing at Bernalillo, in the county of Sandoval and Territory of New Mexico, have invented certain new and useful Improvements in W' 'e-Band Stretchers and Cutters, of which the following is a specification.

My invention relates to wire stretching and cutting devices and is particularly applicable to the preparation of wire used for bands to secure bales of hay or other material.

The chief objects of the improvements which form the subject matter of this application are to provide a simple and effective toolfor the purpose stated; to furnish a combined wire stretcher and cutter that will be portable and convenient to operate, and to produce a mechanism having few parts, and that can be constructed at a comparatively small cost.

I accomplish the desired objects by the employment of the apparatus illustrated in the accompanying drawing, which forms a part of this application and in which the preferred form of apparatus is shown in detail in the following views Figure 1 is a front elevation of my improved wire stretching and cutting tool, a part of the operating lever and a portion of the rock-frame being broken away; Fig. 2 is a rear elevation with the parts in operative position; Fig. 3 is a partial top plan view of the machine, and Fig. 4 is a side elevation of the rock-frame.

Referring to the details of the drawing, the numeral 5 indicates a base block, which may be conveniently formed by a short length of an ordinary scantling of suitable dimensions. This base is placed on edge and upon the upper margin is secured a base plate 6, fastened to the base by suitable screws 7. This plate is of the same width as the thickness of the base block, and one end is turned into a coil or sleeve 8. Embracing this end of the said plate is a clutchframe 9, comprising a top-plate 10, having depending flanges or side plates 11, which extend upon either side of the base plate 6 and are provided with holes which register with the bore of the sleeve 8. A bolt 13 passes through these holes and said sleeve that will be strong and durable forming a pintle upon which the said clutch frame 9 may be rocked in the manner hereinafter set forth. One of the side plates 11 is prolonged upward, forming an extension 14, to which is pivoted an operating lever 15, the pivot 16 passing through said ex tension. The lower end of the lever is rounded at the heel 17, and the point is elongated to form a too 18. The upper end of the extension 14. is bent inwardly to form a stop 19 for the lever 15. Above the base plate (5 is arranged a cutter bearing plate 20, having one end inserted between the flanges or side plates 11 just beneath the said top plate 10. This inserted end of the cutter plate 20 is turned or rolled to form a sleeve 21 to receive a bolt 22 which passes through the side plates 11, forming a pivot or pintle upon which the cutter plate 20 turns to a limited extent as will hereinafter appear. The opposite end of said cutter plate is furnished with a median slot 23, through which passes a lag bolt or screw 24, which pierces the base plate 6 and enters the base 5. This screw serves to prevent displacement of the end of the cutter plate, and serves as a stop to limit the longitudinal movement of the cutter plate, and consequently the lever 15 and attached frame 9, by engaging the ends of the said slot. Upon the upper face of said cutter plate 20, at a suitable location relative to the clutchframe 9 and operating lever toe 18, is removably secured a cutting member, consisting of a plate or body 25 having a sharp flange or edge 26 upon one end. The said cutting member is secured to the face of the supporting plate 20 by screws 27, thus permitting the member 25 to be readily removed in case of breakage or if the tool becomes dull, and another substituted. This cutter is made of hardened steel, and the lower end of the lever 15, is likewise hardened, at least upon the working surface which coiiperates with the top plate 10 and cutter edge 26 in the manner hereinafter pointed out. The clutch-frame 9 and lever 15 are maintained in their initial or inoperative positions by a tension spring 28, secured through the medium of a link rod 29 to the extension 14 at a suitable point 30, while the opposite end is secured at some point 31 on the side of the base block 5. I prefer to make the frame 9 and its extension 14: of a single piece although it may be constructed of a number of pieces bolted or otherwise fastened together.

Having thus set forth the construction of my improved wire stretcher and cutter I will now describe the manner in which it is operated.

The tension of the spring 28 will hold the parts normally in the position shown in Fig. l, the weight of the lever handle causing the said lever to rest against the stop 19, tilting the toe 18 to the position shown in full lines. The Wire 32, which is to be operated upon, is securely fastened by the free end 32 to a suitable support, such as a strong nail or hook (not shown), and then placed beneath the heel of the operating lever, as shown by the dotted lines representing the wire in Fig. 1. The operator then grasps the handle of the lever and carries the latter to the position shown in dotted lines in said figure, thus clutching the wire 32 firmly between the end of the lever, and the upper face of the top plate 10. A further movement of the lever in the direction of the arrow 33 will exert tension upon the wire 32,- and at the same time will rock the frame 9 011 its pintle 13, the bolt 22 will describe an are about the said pintle, raising the end of the cutter plate engaging the bolt 22 until the hardened edge 26 meets the descending toe 18 of the operating lever, severing the wire 32 which lies between. The position assumed by the movable parts at this stage of the operation is shown in Fig. 2. It will thus be seen that a singlelever movement clutches the wire, then stretches and finally severs it. The released lever and attached frame will then be carried back to the initial position by the automatic action of the spring 28.

Having thus described my invention what I claim as new, is

1. In a tool of the character stated, the

combination with a support, of a frame,

rockable on the support, a lever pivoted on said frame and adapted to engage a member of the frame, a cutter plate hinged at one end to the said frame and having a sliding engagement with the support at the other end, and a cutter on said plate adapted to engage the extremity of said lever when the frame is rocked.

2. In a tool of the class designated, the combination with a base, of a frame rockable on the base, an operating lever pivoted to the frame, a removable cutter adapted to engage the end of said lever when the frame is rocked, and means for automatically restoring the frame and lever to their initial positions.

3. In a tool of the character specified, the

combination with a suitable support, of a frame rockable thereon, clamping means cooperating with the frame to form a clutch, a cutter adapted to engage said clamping means, and a spring to restore the frame to its initial position.

4. In a tool for the purpose specified, the combination with a base, and a frame rockable thereon, of a clamping member pivoted to the frame and adapted to cooperate with the frame to form a clutch, a removable cutter adapted to engage said clamping member, a spring for the frame, and a stop to limit the frame movement.

In testimony whereof I affix my signature in the presence of two witnesses.
